摘要
常用的同步串行通信接口数据传输时存在灵活性差和数据传输速率较低的问题。为此,设计一种新的串行通信接口及其数据传输协议,加入多种通信数据类型和地址预测等功能。利用VHDL硬件描述语言完成RTL级描述,并用TSMC 65 nm CMOS工艺进行综合。仿真和综合结果显示该接口的数据传输速率可达125 MHz,适用于一款32位数字信号处理器。
In general,the synchronous serial communication interfaces often have the problems of low data transfer rate and poor flexibility when transfering data.A fully new serial communication interface is proposed in this paper.A new data transfer protocol is defined,in which multiple data types and the function of address prediction are added.The interface circuit is implemented by the Hardware Description Language（VHDL） and synthesized in TSMC’s 65 nm CMOS process.Simulation and synthesis results coincide with high data transfer rate of 125 MHz,and the design is successfully applied in a 32-bit Digital Signal Processor（DSP）.
